ROLLER-TRACK MECHANISM FOR P'ENDENTS'LiDlNG DOORS:

SPECIFICATION forming part of Letters Patent No. 293,339, dated February 112, 1884.

Application filed May 16, 1883. (li o model.)

vented a new and 'useful Improvement in Roller-Track Mechanism for Pendent Sliding Q Doors,of which the following is aspecification. 3 My invention relates to apparatus by which and on which pendent and sliding doors are operated to open and close; and the object of my improvement is to simplify the construction and operation of such apparatus and to better adapt it for application.

My invention consists, as will hereinafter be more fully described in detail, of a rollertrack for a pendent door, constructed with a" hinge in the top at or near the center of the track, on which hinge the two outer .ends of the track may be foldedor turned upwardly, to enter the space above and at the top of the side 3' ambs of the door-opening, and after having been entered be straightened out and leveled on their end supports and center. made,the roller-track for the suspended doors, and which subtends the. door opening to rest upon the side jambs for support by means of its hinged construction, may be inserted in over the tops ofthe jambs without disturbing the condition of the side walls out-sideof or above the j ambs. y A

My inventionalsoconsists, as will be subsequently detailed herein, in the combination, with a centrally-hinged roller-traok, of an opening made in the under side of the rollertrack where hinged, through which to enter the roller-wheels upon the track, and to hook the doors onto the roller-axles.

My invention further consists, as will be subsequently described herein, in the combination, with a centrally-hinged roller-track constructed with an opening in thetrack where hinged, through which to enter the rollers, and to hook the doors onto the roller-axles, of

an adjustable plate and short rail at each side i of said opening, constructed to close, complete,

and secure said track where hinged, so that it shall be continuous fromend to end for the passage of the rollers and suspended doors.

My invention also consists, as will be hereinafter more fully described, in the applicationof a pair of hinged plates and a stirrup,

Thus

constructed to attach on each side of the slideopening made in the jambsfor the door-passage, said hinged plates and stirrups being applied to support and adjust the track, and one of thetwohinged plates oi'eachpairbeing attached at the side of the slide-opening on the face of thedoor -jambs, at right angles to the slidev passage, and the other hinged plate of each pair being turned inwardly,-so as to be against the interiorsides of the slide-passage. Upon the tops of the turned-in hinge-plates of each pair there is attached, the stirrup, one of the latter on each side supporting one of the two rails composing the track, with the bottom of each stirrup containing a set-screw for leveling and adjusting the track.

-My invention also consists in the construction of the hook by which the doors are hung upon the roller-axles, the details of which will be describedhereinafter.

My invention also consists in the manner of constructing the track-inclosure and in the further combination of the parts as made where performing specific function, as will be designated inthc claims.

Accompanying this specification, and forming a part thereof, arethree sheets of drawings containing ten figures, illustrating my invention, with the same designation of parts by letter-reference used in all the figures.

Figure 1 shows in a side elevation a pairof doors hung to move in a track containing my invention, the lower part of the doors being omitted, the connection of the doors with the rollers and track being indicated by adotted line. Fig. 2 is a perspective of the track shown as removed from its support and folded back on its hinged connection. Fig.3 illus trates a cross-section taken through the rails, track, roller, roller-axle, hook, side supports, and door in part. Fig. 4c shows in a plan View and in an enlarged proportion the under side of the hinged part of the track, with the latter secured in position to use the doors and rollers by means of the adjustable plates. Fig. 5

shows in an enlarged proportion as to comparative size and in perspective one of the adj ustable plates used to secure the hingedparts in position for using the track, the plate being shown-as containing a short piece of rail to complete the track where the opening is made loo . rails, slide-opening for the door,the set-screws,

and their engagement with the bottom of the rails composing the track; also, the hook-shank and part of the door. Fig. 8 is a perspective of the hook by which the door-jambs are suspended on the roller-axles. Fig. 9 is a perspective of a plate which attaches to the top of the doors and throughwhich the hook-shank passes for such connection. Fig. 10 is a perspective of the guide-track placed on the floor at the bottom of the slide-opening in the doorjambs, constructed to engage with a groove in the bottom of the door.

The several factors constituting my inven- 'tion and those with which they connect are designated by letter-reference, and their function explained as follows:

The letter T indicates the track-inclosure, made preferably of sheet or galvanized sheet iron, and constructed with an interior supporting-top, of wood, to which the sheet metal attaches. This supporting-top interior is indicated at B, and as attached to the track-inclosure at b. The lower edges of the sheetmetal inclosure may be secured in any manner to the top plate of the door-opening, but preferably by extending the metal edges of the inclosure under the top plates and attaching them thereto by nails or screws.

The track T is made to consist of the inclosure T and the rails R 1%, which are nailed or screwed to the interior lower edges of the sheet-metal inclosure upon opposite sides at n n, so as to leave intermediately, as indicated at I, a longitudinal opening for the horizontal passage of the hook by which the doors are suspended, or the doors themselves when a short hook is used. At or near its center, as shown at Fig. 2, this track T thus composed of the inclosure T and the rails R R, is divided in two parts, and these are connected by a hinge, H, so that the track ends may be folded for transportation or inclined inwardly and upwardly to enter the openings for the track made over the door-jambs when being put in place. At each of the inner adjacent hinged ends of the track the ends of the rails are cut away, so as to produce at that point an opening, through which the rollers W W may be entered upon the rails, and the hooks which suspend the doors D be hung upon the rolleraxles W the opening so made being indicated at O, and the rails, where cut away to produce it, at r r, part of the sheetmetal track-inclosure being shown at Fig. 2, with one of the hinged ends cut away to show the ends of the rails. W'hen the'track is in place and rollers and hooks connected, the adjacent hinged ends of the track are then raised to a horizontal position, and there held in place by means of the slotted plates I P, one of which is placed at each side of the track, and both of which are oppositely attached adjustably to the under side of the door-opening, top sills, or plates 0 C by means of the slots S in the plates and the screws S. As thus placed, these plates 1? P overlap on the under side the hinged ends of "the divided track-inclosure, and they are each constructed on their inner edges to have at their ends the stirrups d d, for the reception and retention of the short railN, the outer ends of which become coincident with the cut-away ends r r of the others, the position of the short rail relatively to ends of the rails at r 1* being adjusted by means of the slots S and the set-screws of the plates P I, to complete the track for the rollers.

The letter O designates a pair of hinged plates, a and a and G a stirrup attached to the top of the plate a, as shown at Figs. 6 and 7 The letterK indicates a vertical set-screw in the bottom of the stirrups, and there are four of these hinges and combined stirrups used, two being employed at each end of the door-opening, at the top of the latter, and being there oppositely placed. The hinged plate a of each pair attaches to the face of the door opening jambs J J upon opposite sides of the slide-opening, as shown at Figjl, and the ,for the door-passage to be parallel therewith,

so that the sides of the trackmay rest in the stirrups G and therein be adjusted and lev- IOO eled by means of the set-screws K in the bottom of the stirrups.

The letter .F indicates the shank of the hook, by which the doors D D are suspended on the roller-axles W. The lower end of this hook shank passes downwardly through a plate that is secured to the top of the door, the construction of which will be subsequently described herein; and the end of the shank is let into the door, and by means of a side opening secured by the nut a on the shank.

The letter 13 indicates a bearing or box for the roller-axle WV to journal in, and this hookbearing has an opening, I), at its top for the passage of the hook-arm S, and is grooved out vertically on the side adjacent to the shank for the entrance of the latter, as designated by the dotted line Zfof Fig. 8, the bearingsurface for the roller-axle being indicated at i. As thus constructed,the bearing 13 is adapted to hook onto the roller-axles to suspend the doors, and has play enough in the bearingsurface 2' by means of the groove Z to be adjustable thereon.

The letter I designates a plate constructed with the corner-tangs h for attachment, and also for screws for attachment, and is. constructed withan opening, 0 for the passage of the hook-shank. This opening is made tubular by means of a rim that extends above and below the plate, as indicated in the annex figure D, taken on the line as m of Fig. 10, the object and purpose of this tubular-form opening being to produce an elongated bearing for the passage of the hooleshanlnto steady the pendency of the doors.

At M, Fig. 9, there is shown a guide-track, that is placed, when used, at the entrance of the slide-passage A, on the floor, and adapted to enter a corresponding groove made in the bottom edge of the door to guide thelatter into the slide-opening. 'As formerly made, the screw-ears, by which this guide-plate was at tached to the floor, were constructed to offset from the end of the plate, in which position they wereliable to interfere with the prompt engagement of the doorgroove and track. To obviate this difficulty, I construct the offset ears m m for attachment to the floor at the sides of the guidetrack and away from the entering end. As the two-partinc1osure T is thus made to receive the rails for the rollers, and is combined with the hinge H, connecting its adjacent inner ends, its two outer ends can be inserted in over the tops of the door-open ing jambs J J and the track put in place without cutting away the wall at or near the tops of the j ambs, and as this adaptation for application is due to the peculiar construction of these parts, their operation remaining the same whether the combined plate P and short rail N were used to complete the track and secure the parts or some other equivalent means were employed, Hence I do not limit my invention of a hinged two-part track-inclosure, as I illustrate and describe the same, to its combination with the plate I? and combined short rail N.

. Having thus fullydescribed my invention, what I claim, and desire to secure by Letters Patent, is'- 1. In a roller-track for pendent doors, the combination of the two-part track-inclosure T, the rails R R, arranged on the inner, lower, and opposite edges of said two-part track-inclosure, and the hinge H, connecting the ad jacent inner ends of the two-part inclosure for the track, as shown and described.

2. In a roller-track for pendent doors. the combination of the two-part track inclosure T, the rails It It, attached on the inner, lower, andopposite edges of said inclosure, the longitudinal opening I between the rails, the hinge H, connecting the inner adjacent ends of the'said track-inclosure at the top, and the opening 0, made in said inclosure between the rail ends beneath the hinge, as and for the purposes herein set forth.

8. In a roller-track for pendent doors, the combination of the two-patt sheet-metal trackinclosureT, the central top support, 13, of wood, attached to the-interior of said inclosure, the rails R R, attached to the inner, lower, and opposite edges of the sheet-metal track-inclosure, the opening I between the said rails, and the hinge H, connecting the inner adjacent ends of said inclosure,.as shown and described. 7

4. In a roller-track for pendent doors, the combination of the two-part track-inclosure T, the rails R R, arranged on theinner, lower, and opposite edges of said track-inclosure, the hinge H, connecting the inner adjacent ends of the two-part inclosure, the opening 0,

made between the rail ends below the hinged connection, the adjustable plates 1? P, and the short rails NN, constructed to adjust in said plates, and the parts specified arranged to attach and operate as herein shown and described.

5. In combination with a roller-track for ed doors, the combination of the hook-shank F, adapted at its lower end to attach to the doors, and constructed with the offset-arm S, and the hook-bearing B, adapted to hook onto the roller-axle, and constructed with the opening b, and vertical groove 1, for the passage of said hook-shank and offset-arm, as shown anddescribed. i I

7. In a roller-track mechanism for suspended doors, the plate P constructed with the corner-tangs h, and screwopenings for at tachment to the top of the door, and the tubular opening 0 for the passage of the hookshank, as shown and described.
